Low-pTcollective flow induces high-pTjet quenching

Abstract: Data on low-p T hadronic spectra are widely regarded as evidence of a hydrodynamic expansion in nucleusnucleus collisions. In this interpretation, different hadron species emerge from a common medium that has built up a strong collective velocity field. Here we show that the existence of a collective flow field implies characteristic modifications of high-p T parton fragmentation. We generalize the formalism of parton energy loss to the case of flow-induced oriented momentum transfer. We also discuss how to em… Show more

“…Most of the empirical properties of the quenching factor for light-flavor hadrons (magnitude, p T -, centrality-, √ s NN -dependences of the suppression) [ 34] are in quantitative agreement with the predictions of non-Abelian parton energy loss models which assume that the parent parton loses energy by gluonstrahlung while traversing a medium with a large color density. Very large initial gluon rapidity densities, dN g /dy ≈ 1000 [ 35], or equivalently, transport coefficients 3 , q ≈ 14 GeV 2 /fm [ 37,38], are needed to explain the amount of hadron suppression. However, the fact that the quenching factor for high-p T electrons from semi-leptonic D and B decays is as suppressed as the light hadrons in central AuAu (Fig.…”
